Fedora xen - Oct 2007 - Reinstall host, guest management

Hi!

I have a server with two guests (all Fedora 7). Each one has its own partition.

host: /dev/hda1
guest1: /dev/hda2
guest2: /dev/hda3

Suppose that my host fail and I need to reinstall it. After
reinstalling, how can I have access to my 2 guests using tools such as
virt-manager/virsh/xm? or make them run as the were before the host
failed.

When I installed both guests, no configuration file was created in /etc/xen

Thanks in advance.

Regards,

Just re-run  virt-install, passing in the /dev/hda2  as the guest file
system. When the installer pops up, instead of doing an install (which
would overwrite your guest), simply use ''virsh destroy'' to
shut it down
immediately. The neccessary guest config file should now have been created
so you can re-start with ''virsh start'' as usual. 

I intend to add some form of ''virt-import'' tool do make this
more simple,
so you don''t have to do the ''boot the installer &
quit'' trick.
